Detailed ways

In the process of producing ceramics, in order to meet the needs of customers, the coloring material is often mixed with the ceramic base material, so that the fired ceramics have rich colors. The particle size and adhesion degree of pigment and ceramic base material are very important to ceramic color. Existing ceramic colorants include dry process colorants and ceramic blank colorants.

In the preparation method of dry color, the wet ball milling process is often used, that is, the raw materials entering the factory are mixed with water according to a certain ratio, and the ball mill is used for grinding to prepare a certain fineness of slurry, and then spray-dried The tower evaporates the water in the mud, so as to obtain the uniform size granular powder that meets the production requirements. These powders are dry-process colorants, and the particles have a small moisture ratio, low viscosity, and good fluidity of the particles. The ceramic base material and the dry coloring material are evenly mixed by using the dry coloring material mixing machine. The preparation process of dry coloring material is complicated, and spray drying treatment is required, which consumes a lot of heat energy. Moreover, the price and cost of the coloring material used in the dry coloring material coloring mixer are relatively high, because the coloring material is dried and its viscosity is low, and in the process of mixing with the base material, the adhesion to the base material is poor, and it is sintered after mixing. After being made into ceramic tiles, the effect meets the requirements for ordinary ceramic tiles, but for medium and high-grade ceramic tiles, the coloring distribution effect is still unsatisfactory.

A new type of ceramic dry granulation technology is to grind the powder into a very fine dry powder, then send the powder into the granulator and spray water mist, so that the powder and water are mixed with viscosity and Cut and stir to form spherical particles. This granulation method is simple in process and low in cost, but the viscosity of the colorant is high. If a dry coloring material coloring mixer is used for mixing and granulation, the speed is too fast and the mixing space is small, which will cause the colorant to clump together Granulated, will not adhere to the base material, and the mixing effect will not be achieved at all.

Because the price of the color material for ceramic billets is lower than that of dry process color materials, and its adhesion to the base material is better than that of dry process color materials, some enterprises directly use color materials for ceramic billets to mix. However, the color materials for ceramic billets are highly viscous The special characteristics make it easy to form a group by itself when mixing materials, forming larger color particles and poor color quality.

Existing mixing machines for coloring ceramic pigments generally include a mixing barrel and a stirring shaft. The stirring shaft is provided with a helical blade, and the motor drives the agitating shaft to rotate, and the mixture is stirred by the rotation of the helical blade. When in use, the ceramic base material and color material weighed according to the proportion are put into the feed port of the mixing cylinder, and the ceramic base material and color material are mixed with each other through the rotation and stirring of the spiral blade.

However, the stirring shaft of the existing mixer has a fast running speed, and the helical blades are easy to cut and damage the ceramic base material and the pigment particles, destroying the original ceramic base material and the particle size of the color material, so that the adhered ceramic base material The amount of colorant changes so that the fired ceramic cannot form the preset color.

For this reason, the utility model provides a new type of mixing machine to solve the technical problem in the prior art that the screw blade of the mixing machine is easy to damage the ceramic base material and color material particles, and affect the color of the finished ceramic.

When the powder is mixed, the colorant and the base material are tumbled and mixed in the cylinder 11, and a part rotates upward with the baffle 12, and when it rotates to a certain height, the colorant and base material fall towards the bottom of the cylinder due to gravity, covering the front On the powder, the powder is mixed many times during the movement from the feed port 14 towards the discharge port 5, which increases the number of contacts between the color material and the base material, and is fully and uniformly mixed.
